I would personally not trust that particular website. One very reliable safe efficient and cheap website that i have boughten from numerous times is airsoftmegastore.com
These are the top 3 for me: Airsoft GI Ehobbyasia Evike/airsoftpost
Airsoft GI
Tissues
dora
Airsoftmegastore.com
Unfortunately Rite Aid does not sell airsoft guns. But Airsplat.com is a great provider of quality airsoft products and reliable service.
Evike.com
Yeah they are like the kimber of the airsoft world
Its actually called ez airsoft guns, and yes it does exist.
Yes, they area a reputable dealer.
novritsch.com
Both are reliable, it depends on where you live because trinity is on the east coast and gi is on the west coast, personally i prefer gi.
